Now in Reforged:

Battle at Hyjal Summit 1.32dx

Lumber is gained from kills. Use Lumber to buy special items, elite units, and upgrades to supplement your forces. Powerful items may be purchased from a Book of Relics shop. Hero and global unit upgrades are now researched at the altars near Nordrassil for the Hyjal Alliance, or the command centers for Legion. A changelog for this version can be found in the quests tab. Hotfix: Some models should now be properly displayed in Classic mode.
